INHALER Filed July 8, 1963 United States Patent "ice 3,265,067 INHALERMarcel Ehlinger, 28 Rue Schefier, Paris, France Filed July 8, 1963, Ser.No. 293,375 Claims priority, application France, July 25, 1962, 905,029,Patent 1,338,422 1 Claim. (Ci. 128-196) This invention rel-ates toinhalers and has specific reference to an inhaler characterized mainlyin that it consists of a closed vessel containing a medicinal liquid, ofa first duct leading with one end into said vessel and adapted to beconnected through its other end to a power fan for blowing Warm or coldair into said duct, said one end of said first duct being. so arrangedthat one fraction of the air thus blow will lick the surface of themedicinal liquid contained in said vessel While the remaining fractionof this air bubbles through this liquid, and of another duct throughwhich the air loaded with moisture and with the active principles of theaforesaid medicinal liquid is exhausted.

According to a typical form of embodiment of the invention these twoducts are secured in and extended through a lid fitting in asubstantially air-tight manner on the aperture of said vessel.

The lower end of said other duct may open directly into the atmosphere,and if desired a suitable mask may be secured on the outer end of saidduct for breathing the air issuing therefrom.

Reference will now be made to the single figure of the accompanyingdrawing which illustrates a typical form of embodiment of an inhalerconstructed according to the teachings of this invention.

The vessel 1 is closed preferably in an airtight manner by a lid 2, anda first duct or pipe 3 extends through the central portion of said lid 2and projects into the vessel containing a medicinal liquid 7. The outerend of this duct 3 is adapted to receive a power fan or like device 4,and the inner end of the same duct 3 is provided with baflle meansconsisting in a plurality of concentric walls 5, with vertical slots 6in said walls, partially extending above the surface of the medicinalliquid, so as to cause the air blown through said duct 3 to bubblethrough the medicinal liquid, one fraction of this air being only causedto lick the liquid surface.

Patented August 9, 1966 Another duct or pipe 8 has its inner end securedin the lid 2 and its outer end adapted to carry a mask 9 to facilitatethe inhalation.

Of course, the form of embodiment of the invention which is describedhereinabove with reference to the accompanying drawing should not beconstrued as limiting the scope of the invention as many modificationsmay be brought thereto without departing from the spirit of theinvention as set forth in the appended claim.

On the other hand, after removing the mask 9 or even as such the inhalerof this invention may be used as an apparatus for cleansing theatmosphere in a room, or as a humidifier, a diffuser of insecticide ormiscellaneous aerosols, according to the nature of the liquid 7introduced into the vessel 1.

What I claim is:

An inhaler comprising a power fan, a closed vessel, a medicinal liquidin said vessel, a lid closing said vessel, a first duct connected tosaid power fan and extending through said lid, a widened bell-shapedinner end of said first duct which is divided internally by bafilemeans, a plurality of concentric walls in said baflie means, verticalslots in the walls partially extending above the surface of the liquid,and a second duct also extending through said lid for discharging on theone hand the blown air having licked the surface of said liquid and onthe other hand the air loaded with the active principles of the medicinal liquid in which it has been caused to bubble, these two gaseousstreams being mixed by said bafide means to form a mist in said firstduct fed with air under pressure.
